Alum Pieter de Jong started a job at the solar energy company SolarCity in June 2014, shortly after completing Hack Reactor’s apprenticeship program. As solar power steadily grows in popularity, SolarCity is working to improve the user experience by adding features to the company’s customer-facing app, MySolarCity. De Jong built a new feature, called “Time Of Arrival” in the app that allows customers to track technicians as they drive toward the customer’s house.
